Why Do You Swim Faster in the Ocean than in Lakes?

    Did you know that swimming in the ocean is easier than swimming in a freshwater lake? As we know, oceans are a salt water mass of water. While freshwater lakes do not have salt in them, therefore that is why we call them freshwater. Some people do not think about it but, have you ever been swimming in the ocean and you almost just float and move with the waves. Then when swimming in a freshwater lake you feel like you get getting dragged back and you are not moving fast at all. These mixtures are the reasons this happen.
    Salt water is heavier than freshwater. This is because there is more ‘things’ in the water, such as salt. Having salt in the water, changes many things about the overall substance. The substance becomes thicker. The salt is the solute in the water, that is why the water changed. For example, when you add a lot of sugar to your coffee, it can change the coffee leaving some sugar at the bottom. That is also referred as supersaturated.
    Freshwater has no salt in it, making it thinner and lighter. When I found this out, I actually thought that it would be easier because you would slide through the water faster. After reading a article called “Here Be Answers”, I learned that it is harder because the water is thinner, which makes you have to use more force and strength to get through the water. This is also why while riding a boat, you have to fill the gas more in freshwater than the ocean. Different solutions lead to different mixtures, which means your speed in the water will vary.
    In conclusion, different solutions/mixtures of water will completely change your average swimming speed. Thought oceans have much stronger currents, Quora also claims that even thought the current might pull you back slightly, you will still go slower in freshwater.

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Light waves, Mechanical Waves, and Radiation

  By Marc Gabay Waves are a very interesting topic, if you take the time to think about it thoroughly; for example, light waves or radiation. The kinds of light waves from our sun are visible light ways. On average, it takes roughly 8 minutes and 20 seconds for the sun's light rays to reach Earth. That being said, if the sun were to suddenly disappear out of the universe, it would take a little more than 8 minutes before we realized it was getting a bit chilly. Light travels fast, however space is so big and vast that it takes many years even for distant stars, galaxies, and/or planets to even come into sight. As a result of this, as we look onward into space, we're really looking back into time. Light waves are very interesting this way. Next, Another way that light waves are interesting is that they affect the human body in both positive and negative ways. These types of light waves can be UV light waves or infrared waves. Infrared radiation is pretty much just heat. Thi...
